Terrasolid

Terrasolid is a family of Windows applications from a Finnish company that has worked on LiDAR software for more than 30 years. TerraScan is the core module. It classifies point clouds automatically and gives you semi-automatic and manual tools to refine the results. It also vectorizes power line wires, places tower models, analyses danger objects near lines, builds 3D building models up to LOD2, and extracts road features such as paint lines and curbs. Other modules extend the suite. TerraModeler handles surface and terrain models. TerraMatch handles strip alignment and calibration, and TerraPhoto handles orthophotos and imagery. TerraBatch runs processing macros over a network, TerraStereo handles stereo viewing, and TerraSplat views gaussian splats. The software runs inside Bentley MicroStation or Terrasolid's bundled Spatix CAD engine, not as a standalone app. Pricing is public and in euros, and each module is bought separately. You can buy a perpetual licence with annual maintenance at 15 percent of the licence price, or an annual subscription that includes maintenance. TerraScan costs 5,700 EUR perpetual or 1,710 EUR a year. Cheaper UAV and Lite editions cut features for drone or smaller projects. It reads LAS, LAZ, E57 and PLY, and it is widely used for DJI Zenmuse L1 data after DJI Terra. Its main users are survey firms, drone service providers and power utilities that run corridor mapping. The main drawbacks are that a full workflow needs several modules and that it runs only on Windows inside a CAD host. Review sites also show almost no public user reviews.
